Snehk's Dreamlands

I was in school, waiting on front of a classroom for teacher to come. Suddenly my previous teacher appeared. He was a bald man with moustache and was wearing a dark gray suit. He told me that he's back in this school and now we have a lesson. He ordered me to follow him. We went outside, we found ourselves in my backyard. The teacher told me to get a bucket and take it to chicken pens. I did as he said - there was a bucket close to father's carpentry workshop so I took it. There were mashed potatoes prepared for chicken inside. I took it to pens. There was a lot of free space inside, with some containers for food and water. The floor was covered by hay. In a corner I saw my younger sister, sitting near a desk with our old computer. It even has an RCT screen. I thrown out the potatoes to nearby container, asking sister what is she doing. She just said that she played. Then the teacher appeared and told me that I took wrong bucket. I went back to stairs of my house and found a black, completely destroyed, plastic bucket.
